EUGENE KORN, OF SAN FRANCISCO, CALIFORNIA.

To all 'lc/omit 'mayiconccrm' f Be ity known that'iI, EUGENE KORN, a citizen ofthe United Statespresiding at the city and `countyof 'San' Francisco and `State of California, "have invented certain new and useful Improvements inI Grease-Retaining Devicesol` Hats, of which the following is a specification. 1 .f

My invention relates to a device to be ap-l plied inside thecrown of a hat of the creased or soft-crown type, for the purpose of retaining the crease therein.

The object of the invention is to provid sucha device which will be as light as pos# sible and inexpensive to manufacture and easy to apply,but which will have the requisite amount of strength to properly retain the crease in the hat crown; and, moreover, to provide means for retaining the device in position and prevent 'the same from falling ,out of place. ture is of very great advantage, for the reason that, as the hat is handled, the crown receives considerable bending and working,

' and, unless such retaining means is provided', the crease-retaining device is very apt to workgloose and drop off.' This is particularly true in thelcase of the-so-called cloth hats, in.V which the (':royvr/i,Y is very soft and pliable. '.In such. hats, Uthe crease-re taining device must have considerable stiffness, and yet must be suiiicientl'y light to be supported by the relatively soft crown material. i n

These and other, objects will be fully-elaborated in the following specification, in which the invention is described in its preferred form, which form is illustrated in the accompanying drawings. It is to be understood, however, that changes may be made in the, form and construction of the invention, within the scope Vof the claim hereto appended, without departing from. the spirit of the invention. With this in view, the invention will be fully described with reference tothel accompanying drawings, wherein- 'y K Figure 1 is a vertical transverse section 4through aV hat, of the soft cloth type, show-.

ing my improved crease-retaining'device in position.

before being bent to shape to be clamped upon a crease.

Fig. 5 is a side elevation of a modified form of my device.

` bent into U-shaped cross section, as shown in Figs. 1 and 3. The retaining device 3 is cut or stampe fromlrelatively thin sheet metal, preferably aluminum, i'n the form shown in Fig. 4, having two opposite wings '4 joined by a shorter central lportion 5. When placed Within the hat, the device is folded longitudinally of this short central portion 5, to bring the wings 4 parallel to'each other, as shown in Figs. 2 and 3. One of said wings then lies upon each side of the crease 2 of the hat, as shown in Fig. l, and the device, being laterally squeezed, securely clamps said crease and retains the same in position.

The outer edges of the device are ontwardlyfiared, as shownat 6, to form a narrow flange. This flange adds sti fiiness to the device, by resisting bending and buckling strains and also prevents chai-ing of the cloth or other material of th'e hat at the edges of the clamp, particularly at the outer folds 2 of the crease, where 'said cloth or material lies against the longside edges 6 of the clamp.

The wings 4 of the device are provided wit inwardly extending projections 7,

'formed preferably by punching the metal are of particular advantage when the device is used in soft cloth hats, for the reason that 1n such hats, being very pliable, the crowns receive considerable bending and distortion,

.tending to work the clamp loose.

For usc in such hats, it may be advisable toprovide a plurality of retaining projec-iy i tionsf-:rn the Wings 4 of the clamp,.as shown in ig: o, although for stiffer hats one such prbjectionfin each wing is suiiicient.

j Ey making the device with relatively long wings 4, ample support is provided for the` upperfol(v 2 of the crease, at which points *support is inest needed; and the relatively short center portion vreduces the'vveight of the device without detracting from its strength, for the bending at this point provides the yrequisite stiffness. The retaining projections 7, moreover, are preferably positioned slightly below the center, to 'bring them nearer the bent portion 5, as shown,'

somewhat exaggerated, in Fig. 1. Said pro` vJections are thus placed 1n the region of greatest st1.ness,'and are less llable to let go and slip, .upon slight spreading of the wings 4,' than would be the case lif they were nearer the upper edges ol said wings.

'As will be readily seen from Fig. 4, the

device can be completely formed by one stroke of a suitably "constructed die,. the

edges being cut and flanged, and the pre- 'v'jections 7 punched, at the saine operation.

The device is therefore exceedingly cheap t0 manufacture, and, being-flat, occupies the least possible space 1n shipment and storl age; andvfinalfly, being, made of aluminum,

and provided with the lange G, saidlevicc has the least possible weight consistent with tively long .lateral wings joined by a relaf tively short center portion, said center porother and to cause the device to assume a lU- 'shaped cross-section adapted to embrace the tion beingbent upbn itself 'to' cause said wings to lie substantially parallel with each 4.

crease of a hat; a continuous outwardly turned reinforcing ange `l'ormefd around .the

entire edge of 'said device; and inwardly fac' ing substantially eonicalprojections carriedv by' said wings for-engaging theniaterial vclamped therebetween.

In testimony whereof I have signed-my. name to tlns specification 1n the presence of -twosubscribing witnesses.
